2,217,996 A w nooRs'roP Michael J. Sasgen, Chicago, III. M Application September 26, 1939, Serial Claims. (01.292-338) I This invention relates to improvements in doorstops of the pivoted lever type, this application being a continuation in part of my prior application Serial No. 251,522, filed January 18,

, 1939, on which Letters Patent No. 2,194,510 was issued on March 26, 1940.

It is the general object of this invention to provide a new and improved shoe construction for the floor contacting end of the lever of a doorstop of the pivoted lever type. More particularly, it is an object of the invention to provide an adjustable shoe on the floor contacting end of the lever.

Another object is to provide an improved shoe construction embodying a metal reenforcing member and a rubber covering both externally and internally of said member.

A further object is to provide a shoe of simple construction having a substantially watertight connection with the lever and further to provide such a device with means for adjusting the shoe on the lever.

Other objects will become readily, apparent from the following detailed description taken 35 in connection with the accompanying drawing,

wherein:

Fig. 5 is a section along the line 5-5 of Fig. 2 (on an enlarged scale).

Fig. 6 is a perspective view of a metal shoe lomember.

Fig. 'Tis a fragmentary sideelevation of a modified form of the invention.

Fig. 8 is a section along the line 8 8 of Fig. 7.

In said drawing, I0 represents generally a door- 45 stop in which the invention is embodied. The stop comprises a stop lever II pivotally mounted at its upper end by means of a rivet 3| on a base bracket I2 which is adapted to be secured to a door I3 near its lower end and in such position that the lower or free end of the lever II will contact with the floor M to prevent the door swinging in the direction of the arrow I5 on Fig. 1. The floor contacting end of the lever II is provided with a shoe I6 having a rubber covering II including arubber pad I8 at the bottom for contact with the floor.

The basev bracket I2 is formed outv of sheet metal and has a back plate I9 which is provided with holes '20 for receiving screws 2|. bracket I2 is'formed with two pairs of forwardly extending projections, one pair of projections 22 at the lower end through which a'pivoted' pin 3| extends, and another pair of projections 23 at its upper end. The projections of each'of' The these pairs extend forwardly in parallel rela- The lever II is also formed out of sheet metal and is made hollow as shown, among other reasons so that it may be provided with smooth rounded edges 24 and for lightness and stifiness. The seam 25 between the edges of the sheet of which the lever II is formed, extendscentrally at the rear side of the lever from end to end of the lever and these edges are slightly separated for a purpose to be explained.

As shown in Fig. 1, the lever II is rounded out as shown at 26, to aid in stiffening the lever and to give it an artistic appearance. Between the ends of the lever II, the side walls are formed outwardly to provide longitudinally extending transversely rounded ridges or projections 21 in position to be arranged between the upper pair of projections 23 on the base I9 to hold the lever in raised position. The projec tions 23 are provided with vertically extending shoulders 28 against which the projections 21 contact when the lever I I is fully raised. Just in front of the shoulders 28 the projections 23 are provided with shallow vertical grooves into which the rounded projections 21 on the lever snap as the lever reaches its uppermost position.

It should be understood that the projections 23 are quite rigid though they have a slight resiliency, and for this reason the edges of the hollow lever. II are left slightly separated so that as it is raised it can be readily forced to its holding position and without undue wear.

The base 2I of the bracket I2 is turned inwardly at its upper end as shown at, 30 and this gives a finished appearance to the upper end of the bracket. This turned-in wall is formed to fit tightly between the projections 23 and serves to assist in preventing the projections 23 being displaced in use.

In the form illustrated in Figs. 1 to 6, the

ill

shoe I6 comprises an inner box-like shell 33 formed out of sheet metal to provide a hollow projection 34 and the walls of which are spread out and flattened at the lower end to provide a horizontal flange 35- which extends along each side and across the forward end 36. The shell 33 is covered inside and out with the vulcanized on, rubber cover I! which is thickened at the bottom to provide the pad l8 for contact with the floor, and which is preferablyformed with transversely. extending. V-shaped' ridges 31 to assist in gripping the floor.

The upper part of the toe flange 36 is cut.-

away at its middle portion to form a recess as shown at 38, to permit the rubber at this point to be filmly vulcanized to the lower part of the flange 36, both on its bottom surface and on its top surface, and to fill into said recess. The.

opening 39 which is provided in the projection 34 to receive the lower end of the lever II, is slightly larger-in cross-section thanthe lever and this leaves roomwto provide a thin covering of. the rubber within the hollow-projection, as shownwat-Ml. This lining; of rubber is arranged tofit snugly upon the lower end'of the lever and assists in preventing-water or moisture entering between the lever'and the shoe, which would tend to rust same, and the lining provides atight fit between the lower end of the lever and the'shoe and holds the .shoe rigidly in position.

Tosecure the shoe-l6 upon1the lever II, the lower end'of the lever is provided with an elongatedzcentralilongitudinalslot 4! which is enlarged at a pluralityiof pointsto receive a screw 42 which extends laterally through the shoe and the lever. By moving-the screw 42 from one enlargement to another; it is obvious that the lever can be variedfin length to suit the circumstances. The endwalls l34' with the rubber lining thereon serve .to prevent pivotal movement of the shoe on the lever. I I. In fact, the rubberlined hollow projection: 34 engages the lowcr 'end of J the-lever H snugly on all sides so that the shoe.is:held against pivotal movement on the end ofthe lever'regardlessof the position. of the screw 42.

Generally, in installing adoorstop ofthe type illustrated, the screw 42 is placed in the'central enlargement of the slot 41, when'lthea carpenter marks the door. [3 for the location of the at taching.=.screws 22.

In order tov facilitate operation of:' the doc-r stop, the shoe I6 is 1 preferably provided iwith in tegrally, formed laterally extending lugs 43 'molded in the rubber cover. l'lthereof. are positioned so that they.may.be engaged..by the finger of an operator or by: the sole of a shoe for the purpose of pullingtthe lever loose from the position shown in fulllines in Fig. 1. In Figs. 7 and 8; there is illustrated a'modified forrnlof the invention. In this form, ll indicates the lower end of: a doorstop lever, this lever: being provided T with three equally spaced Thus, after the bracket I9? has been attached to" the door, theshoe may These lugs.

openings 44. A shoe 45 is formed from sheet metal and has a bottom portion 46 formed by doubling portions of the metal back upon itself, as illustrated in Fig. 8. Flat upstanding portions 41 are laterally spaced and slightly inclined so as to fit alongside the lower end of the lever II when in the position shown in Fig. 7. The upstanding portions 4'! are provided with pairs of openings 48 spaced on centers similarto the-openings Min-the lever so thata pair of screw devices 49may; be inserted to secure the shoe onto the lever. Preferably, the openings 48 in the left hand portion 41 (Fig. 8) are threaded to receive the screw-threads on thescrews.

In this form of the invention, there is provision for adjusting the shoe to either of two positions on-the lever II and in each position the shoe is rigidly secured to the lever by means of the screws 49;. Pivotal movement of the shoe on the lever is sprevented by the screws, each screw functioning to prevent pivotal. movement of'the shoe-.about-the other screw.
